  • A team of scientists from South Korea claimed to develop a material (LK-99) that could act as a superconductor at room temperature.
  • A superconductor is a material that attains superconductivity, a state of matter with no electrical resistance.
  • In a superconductor, an electric current can persist indefinitely.
  • In regular conductors, resistance gradually reduces.
  • But the superconductor’s resistance drops to zero below a fixed temperature, which is the critical temperature.
  • At this temperature, a superconductor can conduct electricity with no resistance.
  • No resistance means no heat, sound, or other forms of energy would be discharged from the material when it reaches the critical temperature (Tc).
